To all whom t may concern.'

Be it known that l, WILLIAM H.. Lrsrr, a citizen of the -United Statesof erica, and a resident of York, county of York, and State ofPennsylvania, have yinvented certain new and useful Improvements inCombined Safety Razors and Stroppers, oi' which the following is a fulland clear specilication. 4

'lhis invention has relation to that type of combined razor and stropperin which the blade is released from the guard and alholder during thestropping operation, the stropper being on the order of the well-knownoscillating-` blade type, forth.

In the drawing- Fig. 1 is a vertical sectional view of my deviceadjusted for use as a stropper;

Fig. 2 is a vertical sectional View taken at right-angles to Fig. 1;

Figs. 3 to 8, inclusive, are detail views hereinafter more fullydescribed.

Referring to the one sheet of drawing annexed, 10 is a handle attachedto the upper end of which is a cross-bar 11 of al frame, the framehaving upstanding sideplatesl 12, this frame being desirably made of asingle sheet of metal, as shown in Fig. Ll,

as more fully hereinafter set which is stamped up to bring the:frameplates 12 at right-angles to thebar l11. yAt the bottom corners ofthe'side-plates, outward depressions 13 are formed therein to providesockets for the ends of rollers 14 which, together with a central roller15, form the guide for the strop 16.

Journaled in the upper part of the frame, with its axis in the samevertical plane with the axis of roller 15, is a hollowroller 17, one endof which is journaled on an inwardly-extending boss 18 on one of thesideframes and the other end of which is journaled, through the mediumof a plug 19, upon pivot-rod 20 connecting the side-plates 12 of theframe, said plug 19 being inserted tightly in the end o' the hollowshaft 17 and being provided with a gear-Wheel 2l which lies in anoutward depression in the adjacent side-frame 12. This gear 21 isadapted to mesh with a gear- 22 affixed to the shaft 23 of the underroller 15, this latter gear 22 being, like gear 21, housed in adepression 24 formed lin the side-plate 12, whereby the two gears arelocated entirely out of the path of the strop andare protected againstinjury.

'lhe ends of the shaft 23 are journaled in cup-like depressions 25formed in the sideplates 12, these journal cups being elongatedvertically so as to permit the rollerl 15 to have a free body movementtoward and from the upper roller 17, the extent of this movement beingsucient to permit roller 15 to drop away iar enough to demesh the gearswhen there is no pressure on the roller 14: from the strop. rlhe roller15 is desirably made or' aluminum, to thereby avoid glazing the4 surfaceof the strop,-and, to still further guard against glazing, l prefer toprovide the face of this roller with one longitudinal groove 26 whichwill present to the face of the strop longitudinal edges which, whenkthe roller 15 is held a ainst rotation in the stropping action, will sightly scrape the surface of the strop. Any number of these grooves 26may be employed; -I believe that two Will be ample.v It will beunderstood that these grooves 26 will come into operation onlyoccasionally, i. e., whenever the two gears are brought into mesh insuch manner as to bring one of the grooves 26 at the under side of theroller at the time when `said rollers cease' to rotate and the strop issliding under the roller. It will be understood that there need be noyattempt on the part of the user to adjust the roller 15 so as to bringthe scraping-edges into action, as these edges need not be brought intoaction every time the stropperis used, it being suilicient' that theycome into use a certain percentage o, times in .the course of use of thestropper; for instance, l believe that yunder the laws of chance one 'ofthese scraping grooves will come into use about on an average of once inevery 24 times the stropper is operated, and I figure that .that will beamplysuiiicient to prevent glazing the surface of the strop in viewofthe fact that it is obvi- ,ous that glazing can be prevented b anoccasional scraping or roughening oi the surface of the strop.

The hollow roller 17 is provided with any suitable form of blade-holdingmeans. In the present instance, I show a pair of sheetmetalclamping-plates 27 which are desirably formedl integral with the hollowcylinder 17, these plates being connected together near their junctionwith the cylinder by one or more rivets 28, the plates being, of course,resilient. The shaving-blade 29 is held between the plates 27. Thisblade isprovided at each end with an inwardly-extending notch 30 havinga Veshaped mouth 31. lhese slots 30-31 are adapted to engage a pair ofspring-actuated lock-lugs 32 ycarried by one of the plates 27 andextending throughl registering slots in' the opposite plate, theselock-lugs 32 being Vshaped. In Fig. 6 I show these lugs as being carriedby spring-arms 33 riveted to the exterior of the bottom-plate 27 ,Y theV-shaped lugs 32 extending upwardly rthrough the slots in said plates,across the .space between the plates and in such position as to beengaged by the slots 30-31` in the blade when the blade is pushedendwisely into the space between the plates 27. These arms 33 aredesirably connected together by a bar 34 and are secured in place by theaforesaid rivets 28. In Figs 8 I show a slight modification; in thisform, the spring-arms 33 are formed by slitting the under-plate 27. Withthis construction, itwill be seen that when the shaving-blade is shovedend-wisely into thel holder, the inner end wall of the notch 3() willstrike against the beveled edge of the nearest locklug 32 and cam thesame far enough upward'- ly to permit the blade to pass; then, when thenotch 30 at the far end of the shavingblade engages the lock-lug 32 atthe opposite side, the previously-raised lock-lug will drop into thenearslot 30 and thus lock the blade against movement in any directionwhile in the holder. The blade may be removed by forcibly pulling itendwisely in either direction. The stropper operates in the usual Whenthe strop is inserted through the system of guide-rollers, thedriving-roller 15 will have its gear 22 forced up into mesh with thecompanion gear 21 and then, as the stropper is pulled back and forth onthe strop, the gearing will cause the blade-holder to flop from one sideto the other, the driving-roller' 15 being held against rotation afterthe edge of the blade comes against the strop, as usual. To assist inguiding the end of the strop between the guide-rollers when it isinterlaced therein, I provide a dished plate 35 which is fastened on theupper side of the bar 11 and has its side edges extending outwardly andupwardly in opposite dircctions to points near the freely-rotatableguide-rollers 14.

I mount on the upper end of the handle, just below theframe-ba'r 11, aguard-plate 36 which at its outer edge is provided with the usualdown-turned iin ers 37, and, at the side edgesof the guar p1ate, withupturned hooks 38. I rovide means for raising and lowering t isguard-plate on the handle, and, to reventv it rotating on the handle, Imake t e upper end of the handle ybe prevented from rotating thereon.

whereby the guard-,plate may be freely moved up and down on vthe handlebut will A sleeve 40 is mounted on.' the handle and threaded internallyto engage threads on the handle, for the purpose of raising and loweringtheguard-plate, an outwardly-extend ing annular flange 41 being providedat the upper end of the sleeve for enagaging integral depending lugs 42on the guard-plate, lugs 42 being in the form of hooks to engage underthe annular flange 41, so that the retraction of the sleeve 40 willforcibly pull the guard-plate down so as to be out of the way during thestropping operation. The parts are so proportioned that. when theguard-plate is dropped down to the position shown in full lines in Fig.1 and the strop is removed from the stropper, the edge of the blade 29will rest on the upper face of the guard-plate at a point a shortdistance behind the hooks 38; then, when the guardplate is pushed up tothe position shown in dotted lines in Fig. 1, the edge of the blade 29will slide along the upper face of the guard-plate and automaticallyengage behind the hooks 38 and thus lock the blade to the guard.
